找了好久原因，发现是在pom文件里plugin下面多引入了
mybatis-generator-core的 依赖导致；
只需要保留
mysql-connector-java 依赖即可；
注释后修改为如下：
org.mybatis.generator
mybatis-generator-maven-plugin
1.3.7
src/main/resources/generatorConfig.xml
true
true
Generate MyBatis Artifacts
generate
mysql
mysql-connector-java
8.0.21
maybe，是因为mybatis-generator-core.jar这个包里有的类没找到
